Abstract (en)
An imitation candle (10) is made from a translucent material (22) having light transmissive properties similar to paraffin. The translucent material (22) is shaped to appear reduced by burning. An LED (24), or similar high intensity light source, is set in a cavity (26) enclosed within translucent material (22). An amber colored LED (24) produces a light similar in color to candle light. The material (22) diffuses the light emitted from the LED (24) to create a warm, natural looking glow. A randomizing energization circuit (46) varies light emission levels from the LED (24) in a pseudo-random manner to simulate the flicker of candle light.
